Drahy R.V.
Co keby ste nabuduce uviedli aspon jeden taky zdroj ?
to co ste tu predviedol bolo len tlachani do vetru a zaobalene nadavani do
BFU

ale teraz k veci
ohlade tej ram .. myslim ze "nenazranost" KDE je uplne normalna
ale ak sa na to pozriete z blizsia tak

#free
            total       used       free     shared    buffers     cached
Mem:        127420     123536       3884      82964       2768      20700
-/+ buffers/cache:     100068      27352
Swap:       546200      61588     484612

je sice pravda ze mam zabratu skoro cleu pamet ale
vecsinu z toho zaberaju buffre(buffers/cache)  (opravte ma ak sa mylim)
ktore sa automaticky v pripade potreby uvolnia
a takisto vidno ze som na tom so swapom este celkom dobre

size sa (myslim) udava v kilobajtoch
cize doporucujem man free a man top
a ked sa popozerate co vam vlastne tak zere pamet tak (myslim9 pridete na
to ze su to tie "buffre" :))))
